The advantages of cardiovascular interventional procedure are: reduce the possibility of infection, general anesthesia and the time of being in hospital. However, two-dimensional X-ray images provided in the procedure could not provide surgeons the actual structure of heart and precise three-dimensional position of the defect, so it’s not so easy for a new physician to perform. In general, new doctors is led by a senior physician for procedure training, but this approach has some potential dangers, therefore, this study will design a computer simulation of double-catheter training system for atrial septal defect that provides physician a platform to practice and be familiar with the operation of various processes, including learning how to manipulate the catheter to the correct position for diagnosis and treatment.
The system provides the user interface including the records of the operating parameters such as the exerted force on the catheter, the displacement and rotation angle of the double catheter, the processing time required to complete a treatment…etc. In addition, the system can be set or provide the real situation which may be encountered while doing simulations of the treatment, for example, the operating skills of passing through the specific location, if the users accidentally bump into the vessel wall, the simulating training system will generate reverse thrust force to the users so that it can make the simulation more realistic and achieve the training outcomes. In the future, we expected that the system can be applied as a teaching platform in hospital that allows users to practice repeatedly to achieve proficiency results and finally improve the success rate of treatment.
